STORM -WINDOW FASTENER.

T all whom it may concern:

the city of Sherbrooke, county of Sherbrooke,

, Provinceof Quebec, Canada, have invented new and useful Improvements in Storm- Nhndo'w Fasteners, and do hereby declare the following to be a clear and exact description of the same.

The object of my invention is to simplify and reduce the labor required in the placing of storm ii indows and screws, and it consists of a plate of metal so shapedthat by a simple and rapid manipulation the window is tightlyheld against the frame.

In the drawings accompanying this specification each numeral denotes the same parts throughout the whole figures.

Figure 1 is a face view of the plateas it appears when coming out from the cutting die. Fig. 2 is a face view of the plate as it appears when bent to shape, Fig. 3 is an edge view of the plate showing the sash ear in view,

Fig. 4 represents the fastener in position on the frame prior to engaging the sash. Fig. 5

represents the fastener in position to retain My fastener is composed, of a plate I pref.- erably of metal, shaped as shown, 2 are the slots provided with enlargements at the same.

lower end, 4 represents the endiof the plate,'

bent at right angle to the same, and 5 is a projection or ear into which is'a slot 3 also aving an enlargement at its lower end to allow a screw head to pass freely through the The ear 5 is bent at right angle to the face of-the plate I andat an acute angle to the edge of the same plate. The lowerpart of the ear 5 is bent inward at the intersection of the" enlargement in the slot with the slot proper, 6 is'the window frame and 7 the r to correspond to the distance of the slots in the fastener, and 8 is a screwin the sash positioned'to correspond to the slot inthe ear of the fastener.

. The operation of the fastener is as follows:

Y It must be understood thatonce the screws 9,

9 and 8 are in place the are permanently in position, therefore to asten the sashit is only necessary to insert the enlargement in slots2 of the plate I over the head of screws 9, 9 when the enlargement of slot 3 will be apposite and above the screw 8 in sash 7. ow by a plying pressure on the projection 4 of the p ate the screws 9, 9 and 8 willen- Specification of Letters Patent,

a gage the reduced portion of slots 2 and 3 and Be it known that I, WILFRID BOURQUE, of"

the head of the screws being larger than the slots will retain the plate in place. The ear 5 being at an angle to the sash 7, it will be evident that the screw 8 will draw the sash inward towards the frame more or less accord ing to the travelv of the plates, and when a considerable pull of the sash is required a few taps of a hammer on the projection 4 will causethe ear 5 to bind on the screw head 8 and draw the sash 7 very tight on to the. frame .6. Of course it will be understood that a reverse manipulation to that previously described will unfasten the plate and release the sash should it be desired'to release the sash before screws 9, 9 come opposite the enlargement in slots 2,'the screw-8* on the-sash, would re uire to beplaced'so that it would engage t e slot 3 of the ear 5 only when screws 9, 9 have engaged the reduced portion of the slots 2, 2. v

It is obvious of course that-as many plates I I as desired maybe used, the number bein determined by the size and construction 0 the .sash.

Having now clearly described my invention what I claim is.

1. A fastening device for window sash,

etc., comprising, in combination with a win-.

dow'frame and sash, headed projections upon said frame, a fastening plate movably' mounted upon said frame and en aged by said projection, said plate having a wing which is slotted, a headed projectionupon the sash adapted to enter saidslot as the plate is moved and frictionally engage said wing, as set forth.

2. A fastening device for window sash, etc., comprising, in combination with a win-T dow frame and sash, headed projections upon said frame, a. fastening plate movably- 'mounted' upon said frame and engaged by said projectiomsaid plate having a wing ex tending at right angles to the plate, and at an inclination to its length and provided with a slot adapted to receive the headed piojection upon said sash as the plate is m ed, said wing adapted to have a wedging' action against the head of the projection upon the sash, as set forth.
